Title: Torque limit control device in automatic plate thickness control device
Inventor: NARITA MAKOTO
IPC: B21B37/18
Filed: 1984-10-03
Abstract: PURPOSE:To prevent the change in the quality of a product by decreasing gradually the target plate thickness upto a prescribed value together with outputting a torque upper limit signal when the current torque reaches the upper limit value. CONSTITUTION:A torque limit control device 10 closes a contact C with the detection of a limit adjuster 19 when the current torque tau of a rolling mill exceeds the preset upper limit value. With the closing of this contact C, a change signal K of a plate thickness locking-on value is outputted from an output circuit 20 to an integrator 21. The integrator 21 outputs the signal increasing at a fixed rate as time passes as the correction quantity of the target plate thickness. This plate thickness correction quantity performs the action so as to reduce the target plate thickness at that time, reducing the output S of an automatic plate thickness control device 4, opening the upper and lower roll gap of a rolling mill and reducing the current torque tau. The adjustor 19 opens the contact C, then, with detecting it and the output of the integrator 21 is kept constant and the quality change of a product is prevented.

Title: Swivel type thruster
Inventor: HIGASHIHARA HIDETAKA
IPC: B63H25/42
Filed: 1982-11-24
Abstract: PURPOSE:To obtain a small-sized thruster in which adjustment is easy, by coaxially arranging a clutch part at the top edge of a thruster input shaft installed vertically onto the platform of a hull and installing a strain gauge, thus reducing the space occupied by a clutch case. CONSTITUTION:The clutch part 11 of a swivel type thruster 8 is coaxially installed at the top edge 25a of a thruster input shaft 25. Therefore, the space occupied by the clutch part 11 is reduced on the upper surface 21a of a platform 21. Since the distance between the upper surface 21a of the platform 21 and the center line of a horizontal input shaft 10, namely the height H of the input shaft is reduced in comparison with the conventional, the inclination angle of a universal joint can be reduced, and the transmission efficiency can be increased. Further, a strain gauge 35 is installed onto the thruster input shaft 25, and a gear case inspection eye 36 is installed at the corresponding position. Thus, adjustement of the vertical degree of the center line of the thruster input shaft 25 during or after assembly is facilitated.

Title: Measuring device for optical path length
Inventor: BAN MINOKICHI
IPC: G01B11/06
Filed: 1984-10-03
Abstract: PURPOSE:To measure the distance between surfaces to be inspected irrelevantly to the surface shape without contacting by using a light source which has short coherence distance and splitting light into two, passing the two light beams through respective optical systems and reflecting them by the surface to be inspected, and superposing both light beams on each other and reading interference fringes. CONSTITUTION:The light from the light source 8 is split into two by a polarization beam splitter 19. One light beam is converged on the front lens surface of a lens 1 through an objective lens 24a. The other light beam, on the other hand, is converged on the front lens surface of the lens 1 through an objective lens 24b. A corner cube 21a is moved to equalize the two light beams in optical path length by utilizing variation of interference fringes. Then, the light beams are converged on the rear lens surface and then equalized in optical path length similarly. The optical path length between both lens surfaces of the lens 1 is calculated from the difference between the 1st and the 2nd extents of movement of the corner cube 21a.

Title: Esterification of phenol group-containing carboxylic acid
Inventor: HANSU YURUGEN NESUTORERU
IPC: C07C69/614
Filed: 1984-10-03
Abstract: Carboxylic acids containing phenol groups are esterified by means of (C1-C3)-alcohols in the presence of acid catalysts without the phenolic hydroxyl groups being esterified at the same time by continuously metering an excess of a water-containing (C1-C3)-alcohol into a boiling hot solution or suspension of the phenol-containing carboxylic acid and of the catalyst in a non-water-miscible solvent (for example xylene) and at the same time distilling off a ternary solvent/alcohol/water mixture via a water separator, the metering rate being such that an aqueous bottom phase separates out in the receiving flask and the water content of the alcohol being so apportioned as not to breach the bottom limit of 0.1% or the upper limit of 1% (based on the contents of the reaction vessel) at any time in the course of the reaction. In this process, the esterification products are obtained free of major impurities and frequently can be used further without further purification.
